TELLERS WINDOW.

SPECIFICATION forming part of Letters Patent No. 774,190, dated November 8, 1904.

Application filed March 22, 1904. Serial No. 199,502. (No model.)

To all 1117110171, it may concern:

Be it known that I, EMERY LIBERTY, a citizen of the United States, residing in the borough of Manhattan, city of New York, county and State of New York, have invented certain new and useful Improvements in Tellers VVindows, of which the following is a specification.

The present invention relates to improvements in tellers windows and means for opening, closing, and locking the same.

The objects of the invention are to provide a window which may be opened for the passage of parcels too large to be passed under the wicket and which will be automatically closed and which cannot be forced open from the outside.

Another object of the invention is to provide a window which will be locked when closed and in all positions of opening and which when partially opened cannot be opened to a greater extent except by the mechanism actuated by the teller.

Another object is to produce a device for accomplishing this purpose and which will be noiseless in operation.

I accomplish these objects by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a front elevation, partly in section, of the window, the wicket, and the mechanism for operating the same. Fig. 2 is avertical section taken on the lines 2 2 of Fig. 1. Fig. 3 is an enlarged horizontal section taken on the lines 3 3 of Fig. 1. Fig. 4 is a front elevation of the mechanism, partially in section. Fig. 5 is a sectional view of the same, taken on the lines 5 5 of Fig. 3; and Fig. 6 is a rear view of a portion of the actuating mechanism.

In all of the views like parts are designated- The wicket 1 is free to slide vertically within the opening 1. It normally rests in the position shown in Fig. l, with a sufficient space between the bottom of the wicket and the counter for the passage of small articles, such as are ordinarily exchanged between the teller and the persons outside of the counter. The wicket may be elevated by mechanism about to be described, so that the space between it and the counter will be suflicient for the passage of large parcels. The wicket sliding vertically in guides cannot be easily forced inward by pressure or a blow from the outside, as is the case with wickets that are hinged and opened inward, as is customary.

The mechanism for elevating the wicket comprises two gear-wheels 8 8, journaled upon a frame 9 9, connecting the sides of the frame 2 2 and meshing with the racks 7. Upon the shafts 10 of the wheels 8 are smaller gears 11, and these gears are connected to the gears 8, so that the latter will be rotated by them. The gears 11 intermesh with the racks 12, carried by a sliding plate 13, which is connected through a chain or rod 14 to a pedal 15. By depressing the pedal 15 the plate 13, and with it the racks 12, will descend, the pinions 11 and gears 8 will be rotated, and the wicket elevated. By meshing the racks 12 with the small pinions, transmitting motion from them to the large gears 8 and from there to the racks 7, an amplified motion is secured, and the pedal will have to be depressed but a short distance to elevate the wicket to the full height. The wicket will descend, owing to its own weight, upon pressure being removed from the pedal. The plate 13 is provided with dovetail guides 16, which engage within ways of similar shape formed within the plate 9, so that the plate 13 will be guided in its upand-down movement and the racks 12 will always be in mesh with the pinions 11.

In order that the wicket may be locked when lowered and cannot be raised except by actuation of the elevating mechanism, a locking device comprising dogs 17 pivoted to the plate 9, is provided. These dogs have rightangled engaging ends 18, which engage with the teeth of small pinions 19, which latter are in mesh with the gears 8. The dogs are normally engaged with the pinions by means of springs 20 Each dog is provided with an extension-pin 21, which engages with the sides of a vertical slide or cam-plate 22, carried by the plate 13. This slide is formed with notches 23, within which the extension-pins 21 will engage in the position shown in Fig. 1. These notches are provided with inclined upper surfaces 2 1. (Illustrated in Fig. 6.) The journals of the pinions 19 are supported in slots 25, which slots are inclined, as shown, and each is drawn upon a circle the center of which is the point of pivoting of the gear 8. A spring 26 normally elevates the plate 13 and pedal.

As before stated, the pinions 11 are connected to the gears 8; but they are not connected directly, but through a mechanism which allows them to turn to a certain extent independently. This lost-motion mechanism is constructed as follows: Upon the hub of each of the gears 8 is a pin 27, which will turn in the path of a pin 28, carried by the pinion 11. These pins are normally mutually arranged, as illustrated in Fig. 4, in which they are separated a short distance. This permits a pinion 11 to rotate to a slight extent before imparting a motion to a gear 8, and permits the former to be rotated almost an entire revolution in the opposite direction before rotating the latter. The racks 12 are preferably as long as the circumference of the pinions 11, so that the latter will be rotated once by the depression of the rack 12.

The operation of the locking mechanism is as follows: Upon the plate 13 being depressed by the pedal the pins 21, which normally rest within the slots 23 and cause the dogs to engage with the pinions 19 and prevent them and the gears 8 from turning, are disengaged by being slid up upon the inclined portions 24: of the notches 23, as shown in Fig. 6, disengaging the points 18 of the dogs from engagement with the pinions 19. The downward movement of the plate 13 will carry with it the racks 12 and will rotate the pinions 11. The pins 28, carried by the latter, are normally in the position shown in Fig. 4:, so that they will not engage with the pins 27, which are carried by the gear-wheels 8, until the dogs 17 have entirely disengaged themselves from the pinions 19. The pedal continuing to be depressed the wicket will be raised untilit reaches the extreme point of upward movement. Upon pressure being relieved from the pedal the spring 26 will first raise the plate 13 to the extreme point of elevation, the pinions 11 freely turning in the backward direction without resistance. This upward movement of the plate 13 will engage the pins 21, carried by the dogs 17 with the notches 23, and engage the dogs with the pinions 19. The wicket will be free to fall as the gears 8 turn freely upon their axles, the

axles of the pinions 19 will rise in the slots 25 and allow the teeth of the gears 19 to slide past the dogs, which act like pawls and ratchets, but with less noise. When the wicket has dropped to the lowermost point in its movement, the pinions 19 will still engage with the dogs and with the gears 8 and the wicket will be firmly locked against elevation, so that if a person from the outside of the window should attempt to raise the latter before it is fully closed the reverse movement will be imparted to the wheels 8 and cause the pinions 19 to drop to the lowermost point in the slots 25 and firmly lock them against rotation by engagement with the dogs 17 The lock just described and consisting of the dogs and pinions is ready to act at any point to protect the wicket from being elevated by means other than the mechanism described. This feature is one of great importance, as it prevents the wicket being opened from its outside before it is fully closed.

As an additional means for elevating the wicket, a hand-crank 27', attached to a shaft 28' and carrying a pinion 29, may be employed. The pinion 29.intermeshes with a rack 30, carried by the plate 13, a slot 31 in the latter permitting the shaft 28 to have a bearing upon both of the plates 9 and 9. The crank 27 by being rotated will raise the plate 13 in the manner similar to the action of the pedal.

Instead of the spring 26 connecting the plate 13 with the frame of the window a spiral spring 32 may be employed, which spring may be carried within a box or casing 33 and will tend to rotate the shaft 28 and elevate the plate 13, and to assist the elevating mechanism counterweights'34, working within the posts 2, may be used, such counterweights connecting with the wicket by means of wires or chains 35, which pass over guide-pulleys 36. These counterweights should not be sufficiently heavy as to appreciably retard the descent of the wicket, but will assist the elevation of heavy wickets.

The action of the pinions 19 upon the teeth of the gears 8 makes less noise than a pawl and ratchet, and for this reason they are preferred.

Ordinary wickets, such as I am familiar with, are hingedv to the window, and are provided with a latch or lock, by means of which they are kept closed. Owing to the extreme width of counters now used in most bankinghouses it is more or less difficult and frequently becomes irksome for the teller to close the wicket every time after it has been opened. For this reason he is frequently tempted to keep the wicket unlatched, which is a very dangerous practice. By my invention the wicket being elevated by pressure of the foot or by rotation of the handle will be automatically closed as soon as pressure is removed from either. Hence there will be no tempta- IIO tion on the part of the teller not to close the wicket. Should a person on the outside of the counter attempt to lift up the wicket while it is descending, his action will be prevented by means of the dogs and pinions, as before described. The attention of the teller will be immediately attracted to this, as he at once sees that the wicket has not closed, and he will be in a position to take measures to insure safety.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. The combination with a window, of a wicket movable therein, means for locking the wicket against open movement irrespective of the position of the wicket, means for discngaging the lock and positively opening the Wicket, means for closing the wicket, and means for locking the wicket against open movement during the closing movement, substantially as described.
